Obviously, your information may vary.

The page is messy but all the information is there if you look hard enough. Each 
mux (multiplex) has a name (or more than one name :)) and the channles it 
carries are shown The information highlighted in green is the actual frequency 
together with the 'channel number' which is the old analog channel, of course.

Lower down is a table (Transmission Frequencies) which lays out how the muxes 
are organised. Good luck!
